Seems to me that's a fairly limited right to access for legal/misuse/safety purposes, not to send you ads for that kinky stuff you looked at yesterday. ;-)

In any case we've known forever that "there ain't no such thing as a free lunch" so if service is given away year after year then either it's the Hare Krishnas or the vendor is extracting value by some other means, usually to do with the customer base. So far it's still easy enough to remain anonymous if you really want to, even if you live outside Europe.
